error message as TEXT is Formatted

Dear All,

Issue is regarding the Text determination.

As I have created a text id, at sales document header level, assigned to procedure n access sequence too.

while creating the sales order, while entering a particular text, the text field is grayed out and message pops up as TEXT IS FORMATTED -> DETAILS. Aa I am unable to enter the text for this particualr ID.

I/p will be of great help n rewarded too.

With Regards,

Vijayashree
